Before people get too far along on their high horses for Clubsprint rules - lots of people on here have mentioned the ban on canards, splitters and diffusers but there is no where in the rules where it states these can't be run in Clubsprint.
The only thing is states must basically be "stock" from a body perspective are guards, doors, boot lids and roofs.
I think the "spirit" of the Clubsprint rules is that those other things are supposed to be banned but no-where does it specifically state this is so. There are a few other vagaries in the rules as well.
Interiors for example:
Interior
• Interior must remain as it came from the factory with the following exceptions
• Front seats may be replaced with an approved seats.
• Rear seats may be removed.
• Carpet may be removed.
• Stereo may be removed.
• Air conditioning may be removed.
• Local modification to interior for fitment of a roll cage is allowed.
So where do after market steering wheels fit into this? I'm running an after market wheel and so did check if it was ok and I was told that was fine but reading those rules you wouldn't think so. Maybe all things need is further clarification before people point fingers at ineligible cars.
